At which point of projectile motion I potential energy is maximum II kinetic energy is maximum?

At which point of projectile motion I potential energy is maximum II kinetic energy is maximum?

It will be maximum when the height will be maximum i.e. at the top point of projectile or at time T/2 where T is the time of flight. ii)The kinetic energy is maximum when the velocity is maximum. So it will be at the starting of projectile(t=0) and the end of projectile(t=T).

What is the angle between the directions of velocity and acceleration at the highest point of a projectile path?

90∘
At the highest point, velocity is acting horizontally and acceleration ( = acceleration due to gravity) is acting vertically downwards. Therefore, at the highest point the angle between velocity and acceleration is 90∘ .

At what point kinetic energy is maximum?

At equilibrium, the kinetic energy will be maximum because velocity is maximum at this point. When the objects move faster than the objects have the highest kinetic energy.

How do you find maximum kinetic energy in projectile motion?

If m is mass of the projectile, it’s kinetic energy at the maximum height will be K=(1/2)mu^2cos^2( theta).

When a projectile is at the highest point on its trajectory the potential and kinetic?

When a projectile is at the highest point, the vertical component of velocity is zero. It only has a horizontal component of velocity. This means that the Kinetic Energy of the object for the vertical component will be zero and all of this energy would have got converted into Potential Energy.

When a projectile is fired at an angle wrt horizontal with velocity u then its vertical component?

The vertical component goes on decreasing and eventually becomes zero.

Why is it maximum kinetic energy?

The two factors affecting maximum kinetic energy of photoelectrons are the frequency of the incident radiation and the material on the surface.

What is projectile A projectile is fired?

Answer: Projectile is an object projected with some velocity and its initial direction of motion makes an angle α ( α >0 and α <90°) with horizontal direction. Projetile moves in a two dimensional plane so that at given time it has vertical displacement as well as horizontal displacement from the point of projection.

When a projectile is fired at an angle theta with the horizontal with velocity u then its vertical component?

What happens to kinetic energy at the highest point of projectile motion?

At the highest point during the projectile motion, the vertical component of the velocity becomes zero, and only the horizontal component survives, therefore the kinetic energy at the highest point is only because of the horizontal component of the velocity and the vertical component of velocity does not contribute to its kinetic energy.

What happens to the energy of a projectile while it’s flying?

Since gravity is the only force acting on a projectile while it’s in the air, then the total energy doesn’t change at any point in its motion, although the energy can change forms from kinetic energy, K, which is the energy of motion, to potential energy]

What is the maximum height a projectile can reach?

Note also that the maximum height depends only on the vertical component of the initial velocity, so that any projectile with a 67.6 m/s initial vertical component of velocity will reach a maximum height of 233 m (neglecting air resistance).

Does a moving object still have kinetic energy at its maximum height?

When it gets to its maximum height, it’s still moving forward, even though its vertical velocity is 0, so it still has some kinetic energy. Let’s see what that would look like on a graph like the one below:
